对 Tasi 群密钥协商协议的改进及安全分析
Improvement and security analysis on Tasi’s group key agreement
摘要
Abstract
Aimed at the security defect of group key agreement protocol for mobile environment proposed by J.L.Tsai,the protocol was improved by using the digital signature technology.That is,some serial numbers were inserted in the digital signatures so as to identify the signatures and the order of the group keys to be generated,and the serial numbers were used as part of public information to verify the digital signatures.So the freshness of messages sent by the mobile users or the powerful node could be checked.According to the security analysis,it is found that the improved protocol not only had the old security properties,but also could resist against impersonation attack or forgery attack.关键词
